improve doc and add note to use higher i2C bus speed #44

Using a higher I2C bus speed to drive the PCA9685 can noticeably speed up motor operation, particularly when many commands are given, such as for stepper motors. Note this in the doc. Also improve the constructor params doc, and fix the formatting of some links.
